Product Overview
The KYN6140.5 armored metal-enclosed switchgear (hereinafter referred to as "switchgear") is primarily characterized by its compact cabinet design. The frame is engineered with a metal-enclosed, armored, and withdrawable structure, and the cabinet is equipped with either a new-generation fully insulated vacuum circuit breaker or a sulfur hexafluoride circuit breaker. Additionally, the cabinet adopts an assembly-based construction, giving the product an aesthetically pleasing appearance while enhancing the precision of the interplay between the handcart and the cabinet. This design enables rapid production and assembly, ensuring timely delivery, optimizing space utilization during assembly, and facilitating easy transition to mass production—all contributing to significant operational advantages.
This product complies with the GB3906-91 standard "Design of 3~35kV AC Metal-Enclosed Switchgear" and the IEC-298 standard "AC Metal-Enclosed Switchgear and Control Equipment Rated from 1 to 52kV."Meaning of the Model
